Abstract: Sclerotia forming time and number were obviously effected by different kinds of media and culture Conditions. Mycelia growth states and sclerotia cultural characters of Morchella conica and Morchella crassipes in different kinds of media and culture Conditions were studied in this paper.The results indicated that the sclerotia of Morchella conica and Morchella crassipes was formed best in 3% malt extract agar of five C sources and in 0.8% complete medium yeast of five N sources. The sclerotia of Morchella conica was formed better at 20℃ under darkness, while the sclerotia of Morchella crassipes was formed better at 25℃ under light . The forming time of the sclerotia was advanced and density of the sclerotia was improved.Mycelial growth and sclerotia forming was improved by sclerotia colonization. Mycelial growth and sclerotia forming of Morchella conica was better than Morchella crassipes,fuseder on density.
